Photothermal disinfection (PTD) offers promising potential for water purification due to its sustainable and broad-spectrum bactericidal properties, although it is hindered by slow charge separation in photosensitizers. Herein, we present a plasma-mediated PTD technique utilizing an efficient localized heating effect induced by incident light at specific wavelengths for rapid bacterial inactivation. A metallic CuS photosensitizer, derived from electronic waste through a biomimetic transmembrane confined-assembled strategy, facilitates collective and coherent oscillation of free electrons around Cu atoms in the near-infrared range.

CsSbBr, as a sort of novel lead-free perovskite single crystal, has the merits of high carrier mobility and a long diffusion length. However, the large-sized and high-crystallized CsSbBr single crystals are not easily obtained. Herein, we apply the vertical Bridgman method to grow centimeter-sized CsSbBr single crystal.

The global increase in urolithiasis prevalence has led to a shift towards minimally invasive procedures, such as retrograde intrarenal surgery, supported by advancements in laser technologies for lithotripsy. Pulsed lasers, particularly the holmium YAG and the newer thulium fiber laser, have significantly transformed the management of upper urinary tract stones. However, the use of high-power lasers in these procedures introduces risks of heat-related injury.

Magnesium aluminates (MgO)(AlO) belong to a class of refractory materials with important applications in glass and glass-ceramic technologies. Typically, these materials are fabricated from high-temperature molten phases. However, due to the difficulties in making measurements at very high temperatures, information on liquid-state structure and properties is limited.
